“unite us into teams, divide us against other teams, and blind us to the truth.”

“As psychologist Jonathan Haidt says, our minds “unite us into teams, divide us against other teams, and blind us to the truth.” It’s that last part that keeps getting you into trouble.

Just as you don a self, a persona, and believe it to be thicker and harder to see through than those of your friends, family and peers, you too believe the groups to which you belong are more complex, more diverse and granular than are groups of which you could never imagine yourself a member.

When you feel the warm comfort of belonging to a team, a tribe, a group – to a party, an ideology, a religion or a nation – you instinctively turn others into members of outgroups, into outsiders.”
